ATTACHMENT FQR LOOIVIS.

Specification of Letters Patent.

- PatentedOct. 7,1913.

Application filed June 22, 1912. Serial No. 705,331.

To all whom it may concern Be it known that I, WALTER A. Woons, acitizen of the United States, residing at Wilmington, in the county ofNew Hanover and State of North Carolina, have invented certain new anduseful Improvements in Attachments for Looms, of which the following isa specification, reference being had to the accompanying drawings.

My invention relates to new and useful improvements in loom attachmentsand has for its object to provide an attachment, which when applied to aloom adapted to weave plain cloth, will permit fancy goods to be woventhereon.

A further object of the invention resides in providing a plurality ofcams adapted to be loosely mounted on the cam shaft and a still furtherobject resides in providing a gear loosely mounted on the cam shaft withwhich said cams are engaged, whereby the latter will be caused to rotateon the cam shaft upon the rotation of said gear.

Still another object resides in providing a device which is extremelysimple and durable in construction, inexpensive to manufacture and onewhich will be very eflicient and useful in operation.

With these and other objects in view, the invention consists in thenovel features of construction, combination and arrangement of parts aswill be hereinafter referred to and more particularly pointed out in thespecification and claims.

In the accompanying drawings forming a part of this application, Figure1 is a front elevation of the device with parts broken away. Fig. 2 is avertical section as seen on line 22, Fig. 1. Fig. 3 is a verticalsection as seen on line 33, Fig. ,1; and Fig. 4 is a similar view asseen on line 4-4, Fig. 3. r

In describing my invention, I shall refer to the drawings in whichsimilar reference characters designate corresponding parts throughoutthe several views and in which- 1 indicates a frame of a loom used inweaving cloth, upon which is rotatably mounted the main drive shaft 2,said'shaft being designed to drive thevarious parts of the loom (notshown) and having a gear 3 mounted on one end thereof. Also mounted onthe frame 1 below the shaft 2 is a cam drive shaft 4 which has anenlarged gear 5 mounted on one end thereof meshing with the gear 3 ofthe shaft 2, said gears 3 and 5 being respectively geared at a ratio of1 to 2 and also carried on the cam drive shaft 4 is a gear (not shown)which meshes with an additional gear 6 which is of similar size carriedon acam shaft 7 which is rotatably mounted on the frame 1 immediately inthe rear of said shaft 4.' This gear 6 is held on the cam shaft 7 whichis of the usual type by means of the set screw 8 and also adjustablysecured to the cam shaft are the usual cams 9 which are adapted toengage the treadles 10 and cooperate with the harness 11 for the weavingof plain cloth.

My improvement comprehends an attachment to this same loom for theweaving of fancy cloth and to this end, I provide an additional gear 12which is loosely mounted on said cam shaft 7. This gear 12 meshes withan additional gear 13 securely mounted on the cam drive shaft 4, theratio of said gears 12 and 13 being 3 to 2, and also loosely mounted onsaid shaft 7 is a plurality of cams 14 arranged thereon in apredetermined manner. In the drawing, I have shown three of these cams14, and while the same are loosely mounted on the shaft 7, they are alsosecured in this predetermined arrangement to the gear 12 by means of thebolts 15. Additional treadles 16 are carried on the frame 1, whichcooperate in the usual manner with the harness 11 and are adapted to beengaged by the cams 14. From this construction, it will be seen that asthe main drive shaft 2 is caused to rotate, the cam drive shaft 4 willalso be. rotated which will, in turn, cause the cam shaft 7 to berotated in view of the intermeshing of the gears 6 and gear not shown.There being an equal number of teeth on these last mentioned gears, willcause the cam shaft to have the same number of revolutions as the camdrive shaft 4 and in view of the fact that the gear 12 and cams 14 areloosely carried on said shaft 7, the latter will merely form a bearingfor the former and will have no material effect on said gear and camsthrough its own rotation. The cams 9 which are carried on the cam shaft7 so as to rotate therewith will engage the treadles at regularintervals and in view of the fact that I have shown a pair of suchearns, the same will weave at every pick of the 100m. In view of thegearing in connection with the additional cams 14, which gearing is inthe ratio of 3 to 2, said cams will be caused to make a completerevolution while the gear 13 on the shaft 4 makes one and one-halfrevolutions and as I have shown three such cams 14, each of which formsone-third of a circle, the respective treadle for each will be held downone pick of the loom and allowed to be retained up or in its ineffectiveposition two picks of the loom. This set of cams 14c is turnedcompletely over every three picks of the loom, and as said other cams 9engage the treadles at each pick of the loom, it will be appreciatedthat the weaving of fancy cloth may be done on the same loom andsimultaneous with the weaving of plain cloth.

In the drawings, I have shown two cams for the purpose of weaving plaineffects and three cams for the weaving of fancy effects, but of course,it will be understood that any number of cams may be used and it will beappreciated that various fancy effects may be woven by the mere changingof the gears and the positioning of the cams.

From the foregoing description of the construction of my attachment, theopera tion thereof will be readily understood that it will beappreciated to those familiar with machines of this character that, theattachment provides a simple and inexpensive means whereby fancy clothmay be woven on the same machine upon which the plain cloth is woven,thus saving considerable labor and general expense.

lVhile I have particularly described the elements best adapted toperform the functions set forth, it is obvious that various changes inform, proportion and in the minor details of construction may beresorted to without departing from the spirit or sacrificing any of theprinciples of the invention.

Having thus described this invention, what I claim is:

1. In a device of the class described the combination with a frame, amain drive shaft rotatably mounted thereon, a cam drive shaft alsorotatably mounted on said Copies of this patent may be obtained for fivecents each, by addressing the Commissioner of Patents, Washington, D. G.

frame, means to drive said cam drive shaft from the main drive shaft,and a cam shaft driven from said last mentioned shaft; of a plurality ofcams adjustably mounted. on said cam shaft and adapted to be rotatedtherewith, a plurality of additional cams spaced from the aforesaid camsand loosely mounted on said cam shaft, a gear also loosely mounted onsaid cam shaft, means to secure said additional cams to said gear atpredetermined points thereon, an additional gear mounted on said camdrive shaft to rotate therewith, said additional gear being meshed withthe aforesaid gear to cause the latter and said additional cams to berotated on the cam shaft, and a plurality of treadles adapted forengagement by said cams.

2. In a device of the class described, the combination with a frame, amain drive shaft rotatably mounted thereon, agcam drive shaft alsorotatably mounted on said frame, means to drive said cam driveshaft fromthe main drive shaft, and a cam shaft driven from said lastmentionedshaft; of a plurality of cams mounted on said cam shaft to be rotatedtherewith and individually adjustable thereon, a plurality of additionalcams spaced from the aforesaid cams and loosely mounted on said camshaft, a gear also loosely mounted on said cam shaft, bolts extendingthrough said lastmentioned cams and said gear to secure the former tothe latter at predetermined points thereon, an additional gear mountedon said cam drive shaft to rotate therewith, said additional gear beingin mesh with the aforesaid gear to cause the latter and said addi tionalcams to be rotated on the cam shaft,

and a plurality of treadles adapted for engagement with said cams.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
